TRANSOM-OPERATOR.

SPECIFICATION part of Letters PatentNo. 312,224, dated February 10, 1885.

Application filed May 14, 1884 (No model.)

To aZZ whom it may concern.-

Be it known that I, SUTTON STRONG, a citizen of the United States, and a resident of Harmony, in the county of Clay and State of Indiana, have invented certain new and useful Improvements in Revolving Sashes orTransom-Locks, and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains .to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a view of a portion of a doorjamb and of a transom-sash provided with my improved lock, showing the lock in edge view. Fig. 2 is a View of the lock detached. Fig. 8 is a View of the portion of the lock secured to the sash. Fig. at is a View of the portion of the lock secured to the jamb, and Fig. 5 is a view of the lockinglever.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to locks for adjusting sashes in transoms or similar tilting windows; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the door-jamb, and B the sash, and a plate, 0, having a straight edge, D, a pro- 'ectin 'lu or )in E and a se mental ed e F, concentric with the pin, is secured upon the side of the door-jamb, flush with the surface of the same, forming a segmental groove or recess, G, inside the segmcntal edge, the inner side of which groove or recess forms a segmental cogged rack, H.

A casing, I, of the same shape and size as the plate, is secured to the sash, and is provided with a flange, J at its edges, which bears against the face of the plate upon the jamb, and the casing has a curved slot, K, opening from the straight edge of the same, the inner end of which slot forms a bearing, L, concentric with the segmental edge of the casing, adapted to receive and form a rocking bearing for the lug upon the plate upon the jamb. The flange of the casing is cut away near one end of the segmental edge of the casing, as shown at M, and two lugs, N, project from the edge to the same height as the flange-a distance from-each other-and the plate has a V-shaped slot inside these lugs, the point of the slot pointing toward the central bearing of the casing. Two lugs, O 0, project from the inner open side of the casing at the ends of the V-shaped slot, between the same and the central bearing, and two pairs of lugs, P P, project from the inner open side of the casing, one pair in the corner of the casing between the V-shaped slot and the straightedge of the casing, and the other pair of logs near the end of the segmental edge of the casing, and two springs, Q Q, are held at their inner ends between these two pairs of lugs, projecting with their free ends over the ends of the V-shaped slot, and bearing against the lugs at the ends of the said slot.

R is the locking-lever, which consists of an outer handle, S, a middle portion, T, having two curved slots, U U, sliding upon the lugs at the edge of the casing, and provided with a laterallyprojecting lug or tooth, V, which engages the segmental rack of the plate upon the jamb, and an inner heart-shaped end, \V, provided with a lug, X, which projects into the \l-shapcd slot and rocks in the same. The springsin the casing bear with their free ends in the shoulders formed by the heart-shaped inner end of the locking-lever, forcing it back into the position in which the lug upon its inner end is in the point of theV-shaped slot, when the lug upon its middle will be engaged between two of the cogs of the segmental rack upon the plate upon the jamb. It will now be seen that when the plate upon the jamb is secured in its place and the plate for the sash is secured in the edge of the sash the curved slot of the latter plate or casing may he slid upon the lug upon the plate upon the jamb, when the tooth or lug upon the middle of the locking-lever will engage the segmental rack, holding the plates in their relative positions, the saidlug or tooth sliding in the groove outside the segmental rack.

\Vhen it is desired to tilt the transom, the locking-lever may be either tilted upward or downward, depending upon the side to which it is desired to tilt the transom, the lever and transom being tilted to the same side, when the lug upon the lever will be disengaged from the rack upon the jamb, and the transom may now be drawn or pushed by the lever until in its desired position, when the lever is released, and when the springs in the casing will force the lever into its normal position, with its inner lug in the apex of the V-shaped slot, and with its lug or tooth engaging the rack.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination of the janib-plate formed with a segmental grooved edge, a cogged rack inside the said groove, and a lug or pin concentric with the said edge and rack. the flanged sash-casing shaped similarly to thejanib-plate, formed with the curved slot and bearing, the l V-shaped slot, the lugs at its segmental i edge, and the spring-holding lugs, all as described, the springs held at their inner ends bythe spring-holding lugs, and the lockinglever consisting of the handle, the central portion having the curved slots rocking upon the lugs at the edge of the casing, and having the rack-engaging lug, and the inner heart-shaped end provided with the lug sliding in the V- shaped slot, and having the springs bearing against the shoulders formed by it, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto at'fixed my signature in presence of two witnesses.

SILAs R. TERRY, FRANK H. EATON.
